Tube mount for Dyson accessories

I've tried some different tube mounts for my Dyson but not been pleased and made my own version based on inspirations from other makers (unfortunately I do no longer have the sources but thank you all!). The two main thing I've done are adding a chamfer to make it easer to attach the accessory and made a screw attachment instead of snap on.

Assemble with four M3x8 sheet metal screws.
